Optimize memory initialization handling in AOT loader

[no1wudi]

Summary

• Modify the AOT loader and AOT compilation code to optimize memory initialization handling
• Change the AOTMemInitData structure to use a uint8 * type for the bytes field instead of a flexible array member
• Update the destroy_mem_init_data_list and load_mem_init_data_list functions to handle new AOTMemInitData structure, including checking ownership of binary data before freeing it
• This change reduces unnecessary memory allocation when the binary data can be directly referenced from the file buffer

Impact

• Enhances memory efficiency by avoiding double memory allocation for data segments when the file buffer is guaranteed to persist
• No functional changes - the existing behavior of loading and destroying memory initialization data is preserved
• Improves maintainability by making the data structure and related functions more consistent and easier to understand
